SPECIFICATION forming part of Letters Patent No.` 731,434, dated June23, 193. V Application filed October l 1901. Serial No. '78,21 3. (Nomodel.)

To all whom it may concern: ber agitates the oil as it bubbles up there-5o Be it known that I, GROVE COTHRAN, a citithrough and resolves thelighter hydrocarzen of the United States, and a resident of bonscontained in the oil into vapors that Summitville, in the county ofMadison and are conveyed from the said chamber E by a 5 State ofIndiana, have invented certain new pipe F.

and useful Improvements in Apparatus for The carbureting-chamber issupplied with Manufacturing Gas, of which the followingis oil from asuitable reservoir G, and the disa` full, clear, and exact description.charge end of the pipe c within the carbu- The object of my invention isto provide an reting-chamber is preferably kept closed by 1o apparatusfor manufacturing a fixed gas (as a suitable floatvalve d, which opensand distinguished from carbureted air) from oil, closes to maintain agiven quantity of oil in 6o and particularly crude oil or petroleum, bysaid carburetingchamber, according as the separating the hydrocarbonsfrom the solid level of the surface thereof rises and falls. or earthymatters contained in the oil, vapo Arranged, preferably, longitudinallyin the x5 rizing all of said hydrocarbons, andeffecting furnace' A,above the hot-air coils C, is one or a destructive distillate of thesame, so as to more retorts H, comprising a tubular body prevent thecondensation or resolving of said ofadiameter comparatively greater thanthat hydrocarbon vapors back into aliquid again. of any of the othertubular elements of the This I accomplish by the means hereinafterinvention'and of such length that its forward zo fully described and asparticularly pointed end can extend through the front wall of the out inthe claims. furnace, while its rear end terminates within In thedrawings, Figure l is a plan View of a short distance of the rear wallthereof. said apparatus. Fig. 2 is a vertical lcngitu- The ends of thisretort have tubular heads e dinal section of the furnace, taken on aplane and f screwed onto the `same in alinement z5 striking through theretort and feed theretherewith, the outer ends of which are closed of.Fig'. 3 is a plan view of said retorts and by removable end plates e f',which when 75 the superheating-coils arranged beneath the removed opensthe retort from end to end same. and permits the same to be cleaned outby Referring to the drawings, A represents a forcing hot air, steam, orwater therethrough 3o furnace which is preferably heated by gas when thefurnace is not in operation.

through the medium of the series of burners Pipe F extends to a pointvery near ythe 8o B, located in the lower part thereof. A short frontends of the retort, where its extremity g distance above these burnersIprefer to place is reduced in diameter in any suitable mana coil of pipeC, the intake a of which prefner and is screwed into a union h, whichlat- 3 5 erably extends through the front wall of the ter, at a pointjust above said extremity g,

furnace and the outlet b of which preferably is provided with anintake-stub for effecting extends up out of the top of the furnace and aunion with the valve-controlled oil-supply discharges :into a pipe D.PipeD may, if depipe K, leading from the' bottom of the carsired, becovered with some suitable nonbureting-chamber,in such manner as todrain` 4o conducting material, and it extends to a point the heavierhydrocarbons remaining therein over a carbureting-chamber E, of suitableafter the vaporizing of the lighter hydrocar- 9o design and proportions,and enters and exbons. The orifice through which the oil tends in saidcarbureting-chamber to very drains from pipe K into the union h isconnear the bottom thereof, so as to discharge tracted, so as to limitthe supply of oil flowing 45 the heated air therefrom below the surfaceof therethrough. This oil falls on the top ofthe y the body of oilcontained therein. The air extremity g of pipe F and is divided into isforced into the coil of pipes C under presminute streams by thefan-shaped corrugated sure. The air issuing from the dependingtrough-piece. secured to the upper segment of end of pipe D inside thecarbureting-chamsaid extremity g, which directs said minute streamstoapointbeyond the discharge-opening of said extremity, Where they willbe caught as they fall from said trough by the blast of hot carburetedair issuing from the said extremity and reduced to very ne particles orspray.

The end of the union-coupling h alining with pipe F is connected by anelbow i With a nipple I. 'lhis nipple connects the said elbow and thefront tubular head c of the retort, and its lower end extends through asuitable hushed opening in the upper side of said head e into the boreof the retort, where it is gradually reduced in diameter and bent towardthe opposite end of the same, so as to produce practically an injector7c, through which the carbureted air and the sprayed heavierhydrocarbons from the union 7L are discharged With considerable forceinto the retort.

The retorts in the furnace are attained at a temperature of from 500otol,200 Fahrenheit.

' This heatis not only capable of vaporizing all have been contained inthe crude oil,but distils n and destroys all the hydrocarbon vaporsthereof and produces therefrom a fixed gas, which Will not be affectedor condensed by changes of temperature or bythe compression which it isnecessary to employ to force the same from the mains of an extensive gassystem. The gaseous products obtained from the retort are conveyedl by asuitable outlet-pipe O, connected to and projecting upward from the stubon the upper side of the rear head e, to a suitable gasometer.

If desired, pipe K can be provided With a valve K to assist incontrolling the floW of oil from the carbureting-chamber into the unionh, and, if desired, pipes D and F can also be provided with valves m andn, respectively, so as to regulate the air-pressure. If it is considerednecessary to have the pressure, both atmospheric and gaseous, maintainedand yet under perfect control from one end of the apparatus to theother, pipe F may be provided at a suitable point along its length witha rotary blower L. This, however, as Well as the otherpressure-regulating devices shown, can be changed or dispensed with, asdesired.

The heavier hydrocarbon oils can, if desired, be fed to the retort undera suitable pressure Without spraying them, and the spraying of the samemay be accomplished either by the means hereinbefore described or bysubjecting the same to a blast from pipe F Without the use of thereduced extremity g thereof. All such changes I desire to be consideredas contemplating within the scope of myinvention, the most important ofWhich is the retort.
